Vitamin D is a nutrient critical to human health. Vitamin D levels are influenced by diet, exposure to sunlight (ultraviolet radiation) and some disease processes. Testing for vitamin D requires a blood draw and laboratory assessment of levels. Vitamin D status may be related to numerous risk factors, conditions, and diseases. Testing might be performed for a variety of concerns including vitamin D insufficiency, risk of poor bone health, presence of conditions resulting in malabsorption or altered metabolism, and suspected toxicity.
